Title: Improvements in releasing mechanisms for coin-freed vending machines
Filed: 1931-02-27
Abstract: 373,297. Coin-freed apparatus ; testing coins. KJAERSGAARD, C., 68, Bredgade, Copenhagen. Feb. 27, 1931, No. 6253. Convention date, March 3, 1930. [Class 27.] Coin action, mechanical-connection.-In release mechanism for coin-freed machines of the kind. having two gripping members which engage a milled edge coin to effect release of the drawer or the like, one of the said members is secured to a pivoted carrier, rotation of which will effect release, and the other is pivoted on the carrier and rotated by the opening movement of the drawer so that after engaging the coin, the gripping members and the coin move as a whole to effect the release. As shown in Fig. 1, one gripping member 7 comprises a prism of steel secured on a carrier 6, mounted on a shaft 1, and the other an arm 14 of a lever 13 pivoted on a pin 10 on the carrier. A milled-edge coin 21, inserted in a shoot 20 secured to the carrier, is supported by a spring-controlled stop 25, the member 7 and an arm 19 of the lever 13. During the initial movement of the drawer, a lug 4 thereon moves towards the nose 3 of a spring-controlled pawl 2 mounted on the shaft 1, and a pin 16 on the drawer rotates the lever 13 so that the arm 14 engages the coin. On continued movement of the pin 16, the members 7, 14 and the coin move together and rotate the shaft 1 and pawl 2 so as to remove the nose 3 from the lug 4, Fig. 4. Finally, when the arm 15 engages a pin 17 on the drawer the arm 14 moves away from the coin which drops through the shoot 20 to a coin-box. When the drawer is closed, a pin 18 thereon engages the arm 15 and in conjunction with the spring 5 returns the mechanism to the position shown in Fig. 1. If a smooth coin is inserted in the shoot 20, the member 14 slides along the periphery of the coin and the pressure exerted thereon depresses the stop 25 and the coin is forced over it into a return shoot.

Title: Improved treatment of lead chloride and the application thereof in the treatment of lead ores or the like
IPC: C01G21/20
Filed: 1924-03-15
Abstract: Lead sulphate is produced by reacting upon a suspension of lead chloride with zinc sulphate under such conditions that the zinc chloride solution obtained is of more than about 20 per cent strength, or by heating solid lead chloride and crystallized zinc sulphate to 300-400 DEG  C. and extracting the zinc chloride.  A lead zinc sulphide ore may be heated with zinc chloride to convert the lead into chloride.  The chloride is extracted with hot brine containing a little acid, and the zinc sulphide residue is roasted to zinc sulphate and leached with water or dilute sulphuric acid to obtain zinc sulphate which is then reacted with the lead chloride obtained from the brine.  The solution of zinc chloride may be divided into two parts, one part being made up for use again by adding the necessary quantities of zinc sulphate, water, and lead chloride, while the other part is treated with sulphuric acid to obtain zinc sulphate and hydrochloric acid, or it may be regarded as a product in itself, in which case it may be freed from lead by treatment with metallic zinc.

Title: Improvements in and relating to electromagnetic thickness gauges
IPC: G01B7/06
Filed: 1941-05-28
Abstract: 547,958. Electromagnetic gauges; inductance measurements. BRITISH THOMSON-HOUSTON CO., Ltd. May 28, 1941, No. 6820. Convention date, May 28, 1940. [Class 37] An electromagnetic gauge for measuring the thickness of non-magnetic material 18 comprises a magnetic backing member 19 and a, preferably laminated, gauge head 10 comprising an angular yoke 11 with limbs 12 ... 14 having rounded ends 15. Windings 16, 17 on the outer limbs are arranged to magnetize the limb 14 in the same direction and changes in their reactance are thus produced in accordance with the thickness of the material 18. To obtain a measurement, a similar balancing unit 20 is provided, the coils 23, 24 of which are connected along with coils 16, 17 in a Wheatstone-bridge, with the latter pair diagonally opposite one another so as to give a doubling effect on the unbalance. An A.C. supply is connected to bridge-points 25, 26, whereas the output is connected at 35, 34 to a rectifier bridge and d'Arsonval type voltmeter 37. The moving coil M of a dynamometer-type instrument may also be connected across these points, the fixed coil F being connected across source 27 over an adjustable resistance 40, ammeter 41, and phase-shift device (not shown). For calibration purposes, unit 20 is adjusted by screw 22 for balance using a standard thickness between poles 15 and backing 19, and the instrument may then be adapted to read actual thicknesses or deviations from normal. For providing continuous readings of, for example, paper or rubber strip 18b, Fig. 4, passing over a roller 50 having a backing 19b, a straight yoke 10b supports limbs of the shape shown, the outer limbs carrying rollers 51 for spacing them from the strip. The arrangement is also adaptable for a flat backing, Fig. 3 (not shown) and for the determination of concentricity of a composite bar or rod, such as a welding electrode comprising a non- magnetic sleeve surrounding a magnetic core. In all these cases the gauge is employed in the bridge of Fig. 1. Specification 299,296, [Class 37], is referred to.

Title: Improvements in or relating to the preparation of costus root oil and the products thereof
Inventor: KELKAR GOVIND RAMACHANDRA
IPC: C07D307/93
Filed: 1958-03-04
Abstract: The naturally-occurring lactones contained in the costus root are isolated from costus root oil which has been extracted with petroleum ether (see Group III).  The lactones are said to be thermolabile and converted to polymeric and/or decomposition products by other extraction processes.  A lactone melting at 108 DEG C. crystallises out at room temperature and a further mixture of lactones may be obtained by mixing the residual oil with petroleum oil and cooling to between -15 DEG  and -20 DEG C.  The former is designated "costanolide" and has the formula:  <FORM:0866809/IV (b)/1> and the mixture, designated "neo-costanilide" is a mixture of "costanolide" and dehydrocostus lactone of the formula:  <FORM:0866809/IV (b)/2> together with traces of compounds of unknown structure.ALSO:Costus root oil is extracted by treating powdered costus roots with petroleum ether (40 DEG -60 DEG C.) at room temperature, separating the ether extract from the plant pulp by filtration, and removing the ether from the extracted oil under vacuum at a bath temperature of about 40 DEG C.  Extraction by this method is said to avoid the polymerization or decomposition of thermolabile components of the oil, particularly lactones, and to permit their isolation (see Group IV(b)) in their natural form.

Title: Improvements in or relating to high-tension transformers
IPC: H01F27/32
Filed: 1963-02-21
Abstract: 995,168. Transformers. BRATISLAVSKE ELEKTROTECHNICKE ZAVODY NARODNY PODNIK. Feb. 21, 1963 [Feb. 21, 1962], No. 6933/63. Heading H1T. The dimensions of a high-tension transformer may be reduced by the use of insulating pressure rings 3 (Fig. 2) which include capacitative rings 1, 2 and have walls acting as voltage barriers for the end coils 4. The outer insulating side wall may be bulged out to receive the supply cable 6 (Fig. 2). The end coils, treated with synthetic resin, and the capacitor rings 1, 2, are cemented into the insulating ring 3 to avoid ionisable gaps. The inner capacitor ring, inside the pressure ring, may have a channel section 2 (Fig. 4) filled with solid insulating material to form a base for the end coils. Since parts of lower dielectric stress need less insulation, a multiple-stepped inner wall and tapering outside wall (Fig. 5) may cover the end coils. The walls can be extended by cementing on insulating rings 7, 8 (Fig. 6), or laminate cylinders (Fig. 9, not shown) on the outer edge of the coils may be sheathed with a resin-coated, glass or glass-mica tape, or sprayed resin (Figs. 10, 11, not shown). The capacitative rings 4 may be made of metal, semi-conductor, or a combination of conducting and non-conducting materials. The casting materials (e.g. polyesterepoxide, silicone or silicone-rubbers), compounds (e.g. polyester-epoxide resin or silicone elastomers) and binders (e.g. epoxys or silicone resin) have fillers (e.g. fused quartz, chopped fibres or fabric of glass, or mica) to increase the mechanical and dielectric strengths and the thermal conductivity of the insulation. Treatment of the coils with such compounds during or after the winding process, can be effected in vacuum or under pressure, if necessary by centrifugal means.
